(...) Ok, I have to admit that I was wrong. But I think most of the time it is the easiest solution to start all the tasks at the beginning and have them run in parallel. And if you want to perform some single action within a task use a (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx.nqc)

I'm pretty sure there were no filters involved. This was the basic robot arm that can be built from the 9740(?) Control Lab Starter Set for the Serial Interface Box. She slightly modified it so that there were multiple bins for all of the different (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx)

Ben, did this designer use any filters? Or was this simply the response of the LED and detector in the Light Sensor? (24 years ago, 6-Feb-01, to lugnet.robotics.rcx)

Thanks for the replies, and for the sample programs. I'll try them out soon. I'm building a robotic arm (that's why I chose to reply to this message, not the other, later ones) that I plan to program in NQC. It does not need multitasking to work, or (...)

(...) So motor_a_speed(MAX_SPEED) is not enough, since it turns the motor off every 256 ms for a single ms? I have an idea how to change the code to make the output really constant, patch attached. A side-effect of this change is that (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx.legos)

Ok, I'll answer my own question: (URL) I think I saw this a long time ago, but I had assumed that the "Mibo in Book!" link was referring to the Mibo on the cover of a Japanese magazine that Jin Sato had on display at Mindfest. I didn't realize it (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx, lugnet.books)

| | DC output at motor max speed with legOS
|
|
Hi, I am trying to control a stepper motor with LegOS, and I need to have a constant DC output from a motor output, like when I choose speed(8) with the Lego firmware, so I can turn it on and off to make pulses of the duration I choose. Is this (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx.legos)

I saw a 6th grade girl with a lego robot arm that could sort about 10 different lego colors using the light sensor. It was amazing. It wasn't the RCX, but the light sensor was the same. She actually brought in her pink and purple LEGOs from home (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx)

I think a worm gear and a 40-tooth gear worked for me. A string was fixed above, and wound around the axle connected to the 40-tooth gear. This wasn't fast though, more like a slow climb. But I think you definitely want a worm gear or some kind of (...) (24 years ago, 6-Feb-01, to lugnet.robotics.rcx, lugnet.robotics)
